Totally natural, raw egg white. Weird but works.

1. Cheap. Absurdly so.2. Plentiful. You all have it already.3. It works!4. No supermarket embarrassment buying a lube.5. No oil. (don't fry it first).6. Not as weird as you think.7. Easy clean-up.8. Non-staining.9. Dries out surprisingly slowly.10.No cholesterol if you toss the yolk.

This doesnt sound very smart. The bacteria in raw eggs can cause serious illness, and to have the those bacteria in and around the genitals sounds like a fiasta for bacteria. la cucaracha, la cucaracha....
